York is one of the most recognized names in American home comfort, and is a Johnson Controls brand that has been manufacturing residential HVAC equipment for over a century. They continue to design, engineer, and assemble their products in the United States. York residential air conditioners are organized into two distinct product lines: the premium Affinity™ Series and the LX Series. Affinity™ models target homeowners who want the highest available efficiency, the quietest possible operation, and communicating system integration. LX Series models deliver proven York reliability and strong efficiency performance in a more accessible package. Both series carry York’s Good Housekeeping Seal of Approval and are backed by York’s industry-leading warranty program, including Lifetime Compressor and 10-Year Parts Limited Warranties on registered Affinity™ equipment.
